UNFOLD

This is a one-step solver for unfolding complicated parts. UNFOLD allows the user to unfold the selected flange element. The program will automatically add the constraint information and set binder as an option. The UNFOLD dialog box is illustrated in Figure 7.4.1.

 

MATERIAL: Define blank material.

THICKNESS: Define blank thickness.

CURVE BINDER: Define surface of curve binder. This function is optional. If curve binder is defined, the color of button tag is changed from blue to light green.

UNFOLD REGION: Define region to be unfolded. If unfold region is defined, the calculation is automatically activated.

ADVANCED: This option allows the user to change the default setting of advanced MSTEP parameters such as binder force, pad force, friction, and max. iteration step and displacement convergence. Refer to Section 7.3.1  for description about defining advanced parameters.

LINE: Automatically import the unfolded line and display it on the screen upon completion of calculation.

MESH: Automatically import the unfolded mesh and display it on the screen upon completion of calculation.

KEEP INPUT FILE: Keep input deck in the directory.
